Available languages: French, English
Summary:

This document specifies the physical and mechanical properties of fittings made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels.

It also specifies the test parameters for the test methods to which it refers.

The ISO 16486 series is applicable to PA-U piping systems, the components of which are connected by fusion jointing and/or mechanical jointing.

In particular, this document lays down dimensional characteristics and requirements for the marking of fittings.

In conjunction with the other parts of the ISO 16486 series, this document is applicable to PA-U fittings, their joints, joints with components of PA-U and joints with mechanical fittings of other materials, and to the following fitting types:

—     fusion fittings (electrofusion fittings and butt fusion fittings), and

—     transition fittings.



Le présent document spécifie les propriétés physiques et mécaniques des raccords en polyamide non plastifié (PA-U) conformément à l’ISO 16486-1, destinés à être enterrés et utilisés pour la distribution de combustibles gazeux.

Il spécifie également les paramètres d’essai pour les méthodes d’essai auxquelles il fait référence.

La série ISO 16486 s’applique aux systèmes de canalisations en PA-U dont les composants sont raccordés par des assemblages par soudage et/ou par des assemblages mécaniques.
